This creates the particular problem of sufficient bonding of the fiber composite material to the metal. Accordingly, the production of a plastic-metal hybrid component from a metallic base body and a fiber composite semi-finished product made from a fiber composite material having a polymer matrix connected to the base body requires the development of specific joining methods.

Too small proportion of the remainder of the formula (II) leads to an insufficient cohesive connection to the surface of the metallic base body.
